App Store Description
The 555 timer is an integrated circuit chip that is commonly used in timers, pulse generators, and oscillator circuits. The 555 can be used as a delay device, flip-flop or oscillating element in the circuit.
This application is mainly used to calculate the timing circuit output frequency.
Input parameters: R1 (ohm); R2(ohm); C(F)
Output parameters: duty cycle (%), high time (s), low time (s), frequency (Hz)
Calculation formula:
TH (high time s) = 0.693 * (R1 + R2) * C
TL (low time s) = 0.693 * R2 * C
Frequency (output frequency) = 1.44 / ((R1 + R2 + R2) * C)
DCP (duty cycle %) = (T(h) / (T(h) + T(l))) * 100
